RPM Suga

Installed on XJR400R (mid-term).
The installation itself is very easy, even a Custom beginner can do it. RPM has a great sound. It is the best sound for air-cooled 4-shot.
It is a high-pitched sound. The only thing that concerns me is that there is some exhaust leakage from the assembly, and the Instruction Manual says that leakage from the assembly is Spec. I heard that there is no problem with the quality, but if you are concerned about it, you should apply Liquid Gasket.

Also, is carburetor setting required? I think it is necessary. My XJR400R has a tendency to hit the head at high rpm, and the acceleration and top speed become slower.
I changed the main jet from OEM No. 90 to Key Star No. 87, and it improves the blow up, acceleration from the latter half of 5000 rpm, and the maximum speed is increased. I think it will be the replacement of jets.
I am going to take the time to do it because I don't have the Settings out there yet. If you don't want to do it yourself, I think it would be more perfect and faster if you send it to a Shop. View detail

I installed it on my CBR400FF.
Stainless Steel Silencer is better than Aluminum Silencer.
It's a Mischief high-pitched Sound player.
Select Stainless Steel.
I've tried many exhaust systems.
After all, the standard combination RPM is the iron plate.

And you don't need a walleye when you install it.

Satisfied

There's an exhaust leak at the assembly
It was difficult to install!
It's quieter than you might think, so you can ride in peace?
Can I wear the End Baffle? View detail

Is it too loud without End Baffle?

I managed to do the installation myself There is an exhaust leak in the assembly, so Repair with a liquid gasket is necessary
It's a good way to get out of the car, so you'll get a low-mid speed cover Now I'm applying exhaust pressure with End Baffle, so it doesn't bother me so much, but without If you ride with Baffle, you need to adjust the carburetor
After 8,000 RPMs, the engine blows up to Smooth, and the OEM Exhaust System will give you the best results It's comfortable and runs with a race ish sound
The exhaust noise is a blast; the Initial ModelBANDIT is a low 250cc Torque Since it's a four-cylinder, it has to be blown to some extent at Start, and when it is, the explosion is too loud So I can't ride without End Baffle So, I can't ride without End Baffle
Style is a lighthearted Image! The weight can be reduced from the OEM View detail

Yes

It was cheap, it costs no shipping fee, so it will be good soon!
Acceleration has changed at all, and the sound is the best even if it rains!
Please try to buy everyone!

it's the best.

I bought 67 RACING for ZEPHYR 400.
I've been using cheap Short tube, 4-1 tube and various Silencer, but after all RPM is good.
If you turn elegantly from the Idling sound, you will play the sound of the nobility.
As for the high revolution type single car, it is RPM after all.
It will be fun to run. View detail

no, ~ -- although a certain amount of anticipation was carried out, it is explosive sound roaring splendidly (a smile -- it is a word and is like [ which is regarded as a straight pipe or ?? ].)
Although I think whether whether it deals with an automobile inspection is that it is doubtful (impossible probably), I think that it is good for the bottom enjoying a fresh sound briskly.
Existence of Ho of a car body is conspicuous rather than showing the presence of a muffler, since appearance is [ the muffler itself ] thin.
It seems that the model before regulation is generally more popular although the model after regulation has come out now.

Sound is good whatever it may call it after all! It can be heard to the extent that it becomes infatuation, even if this shrill sound has ridden. The fault of a description is severe first. Requiring special attention, since it is too suitable.

Although XJR400 was equipped, since it was a slim style so that it might see and understand, it exchanged from normal and became quite light.
I think that there is quite a many sound volume.
Compared with other manufacturers' thing, it is peculiar, and low-pitched sound sounds and tone quality can also be heard.
Although it is about the important engine performance, since it is 4-2-1, it does not turn easily to high rotation.
Ascent is hard, if it goes to a peak for play since it will be calm if setting is issued firmly, (but) it is.
On the other hand, by town riding, since the low speed is light to a strong top, it becomes quite easy to ride.
It is a recommend at a person with much town riding.
It is better to have rusted, immediately after equipping with it, since the rest rusted easily, and to apply a stop. View detail
